Application tiled February 24, 1912. Serial N o. 679,707.

To all whom t may concern Be it known that I, SIMEON C. LAwLoR, citizenof the United States, residing at Chicago, in the county of Cook andState of Illinois, have invented certain new and useful lmprovements inMop-Wringers; and I do hereby declare the following to be a full, clear,and exact description of the invention, such as will enable othersskilled in the art to which it appertains to make and use the same.

This invention relates to improvements in wringers, and particularly tosuch as are adapted for use in cooperative relation to a receptacleadapted to receive the exuded fluid, the invention being designed moreparticularly for the wringing of mops.

To this end, an ob] ect in view is the provision of means causing theparts of the wringer to assume a position when not in use adapted tofacilitate the introduction ofa mop. l

With this and further objects in view, the invention comprises certainnovel constructions, combinations and arrangements of parts as will behereinafter described and claimed.

In the accompanying drawing,-Figure 1 is a view in side elevation of awringer einbodying the features of the present invention. Fig. 2 is atop plan view thereof.

Referring to the drawing by numerals., '1 indicates a pail or receptaclesupporting base which is formed of a strap 1a set on edge, preferably ofmetal, and cross straps 1b, 1", connecting opposite points of strap 1aand forming the bottom or supporting portion of the base upon which thepail or other receptacle 2 is designed to'be sustained. The base 1 iscarried `preferably on casters 3, 3, whose stems are journaled insupporting brackets 4, 4, each consisting preferably of a metallic strapformed witha loop or bend at its upper end inclosing the strap 1a andextending downwardly and being formed into a loop presenting two spacedhorizontal portions which are perforated for the reception of the stemof the respective vcaster 3. vrlhe upper loop of bracket l is preferablyriveted to the strapla, and the brackets are spaced about the base 1suitably for supporting the same.

Upstanding from each side of the base 1 is a side frame, which, forfacility of manufacture, may consist of a standard 5, and a standard 6,which areinerely continuations ofthe straps 1b, 1", the said strapsbeing riveted to the strap 1a at the lower end portions of thestandards. For facilitating disposition of the operating parts at theupper end of the side frames, each standard 5 is preferably perfectlyupright, that is rises vertically from the base, while each standard 6is formed laterally arcuate or curved to cause its upper end to approachthe upper end of the respective standard 5, and the two standards areconnected by a plate 7 which is riveted to both standards. A cross baror rod 8 connects the two plates 7 having its ends fixed to therespective plates as by a shoulder at one side of the plate, and aswaged head at the other, not herein illustrated. Each plate 7 extendsvertically above the respective standards 5 and 6, and is bent to ahorizontal position across the upper ends thereof, and then again bentto an upstanding position, the last named part of the respective plate 7being slotted, as at 9, forming guiding cani plates 10 and 11. Thehorizontal portion of each plate 7 is slotted, as at 12, for receivingand guiding an actuating arm hereinafter mentioned.

A bail-like lever 13 has its ends pivoted, as at 14, to the standards 6,and its intermediate portion outstanding above the base 1, and providedwith a suit-ably attached tread plate 15. Pivoted to the respectivesides of the bail 13, intermediate the pivot point and the tread plate,are the respective upstanding arms 16, 16,y which extend through and areguided by the respective slots 12, the slots being of a size looselyaccommodating the arms, but of sufficiently snug fit to prevent anyexcessive lateral or edgewise play. Each arm 16 is bent edgewisesubstantially midway of its length, as at 17, for causing the upper endof each arm to travellaterally a greater distance than it wouldotherwise travel for the purposes hereinafter mentioned. It is to benoted also that the connection at the lower end of each arm 16 is spacedfrom the respective pivot 14 a distance suflicient for causing the lowerend of each arm to always remain outside the vertical, transverse planesof the slots 12, so that each arm 16 extends on an inclinelongitudinally through the respective slot. A spring 18 is preferablyarranged lat each side frame and has Lits upper end'c'onnected to therespective standard 6 adjacent plate 7,

A wringer roller 19 extends across from.

one side frame to the .other and is journaled in the plates 11 at oneside of slots 9. A similar roller 2O is journaled in the upper ends ofthe arms 16, one of the journalsofV roller 2O extending Vbeyond therespective arm and being formed into an .operating crank 21. Thejournals of each roller 19, 20, preferably consist of a reduced shaft 22fixed to and outstanding from a disk 23 which is in turn fixed to therespective roller, as by screws 24, 24. Each roller 19, 20, is thussuiiiciently short to lie between the Plates 11, 11, 10, 10, lwithout.end contact therewith, the reduced journals 22 engaging the respectiveplates. The upper edges of the plates 10 are rounded offto form cams orguiding plates, and in .operation are engaged by the respective journals22 during reciprocal movement of the arms 16.

A rod 25 is-carried by each plate 7 and extends inwardly therefrom belowthe rollj ers 19, 20, and is bent bac-kwardly,that is in a directiontoward and beneath roller 19 for serving as mop guides, the said rodsextending over the edges of the pail 2, so as to insure disposition ofthe mop within the pail without necessitating grasping the mop j by thehand of the operator.

In operation, the parts being in the position seen in full lines in thedrawing, the operator lifts the mop merely by the use of the handle ormop stick and lowers the mop clothY between the rollers 19, 20, downinto the pail 2. After the mop has been introduced for its f-ull length,the operator places his foot on tread plate 15 and lowers the lever tothe position indicated in dotted lines in Fig. 1, whereupon t-he partsassume the dotted line position as indicated in both figures. Duringthis lowering movement of lever 13 the arms 16 have been drawndownwardly, being guided first by contact of the front edges of the armswith the front ends of the slots 12 until the journals 22 of roller 2Ohave come in contact with the upper edges of plates 10, whereupon thesaid plates serve as guides, so that the final relative position of therollers, as indicated in dotted lines, is assured. Thus the downwardpressure on the lever 13 tends to draw the roller 2O toward roller 17,and if an interposed mop prevents the full movement of roller 20, thelamount of pressure exerted by the foot on the lever 13 will govern thedegree to which the mopmay be exhausted of its moisture by virtue of thecapacity for varying degrees of pressurey on the mop. As soon as the mophas been iirmly clamped between the rollers, the operator rotates therollers by actuation of crank 2l until the mop has been fed baclwarcllyor upwardly .out of the rollers. Thereupon the operator removes his footfrom tread plate 15, and the lever 13 is drawn by springs 1S back to itsformer position with the connected parts restored to the positionindicatedin full lines.

ltis to be noted that the incline of the larms 16 causes the roller 20to travel forthe other roller, each of said arms being bent intermediateits ends in a direction causing the roller engaging portion of the armsto be disposed awayfrom the fixedly supported roller, guides for thearms surrounding the same, and means for thrusting the armslongitudinally through the .ouides to an extent causing the bentportions to pass the guides, whereby the roller carried bv said arms isadapted to be moved laterally away from the other roller during themovement imparted by the longitudinal thrust of the arms.

2. In a wringer, the combination of spaced supports, a roller journaledtherein, each support being formed with a guiding slot adjacent theroller and with a guiding cam surface leading to the slot, a pair ofarms having their free ends movable past the slot, guiding means for thearms, a roller j'ourn'aledV in the free ends of said arms and havingjournals adapted to contact with and be guided by the cam surfaces intothe slots, and means for reciprocating said arms longitudinally to carrythe second-mentioned roller toward and away from the first-mentionedroller.

3. In a wringer, the combination with a base, of spaced side framessustained thereby, each having a plate formed with an upstanding portionand an offset horizontal portion, the horizontal portion of each platebeing formed with a longitudinal slot, a roller journaled in theupstanding portions of the plates, an arm movable longitudinally andsubstantially vertically through each slot, a roller journaled in theupper free ends of the arms, and a lever pivoted to the side frames andconnected to said arms for actuating the same.

1. In a wringer, the combination of spaced side frames, each comprisingspaced standards, and a connecting plate therefor, each iio iis

L neoted to Jche standards, and each connecting plate being formed Witha longitudinal slot 1n its horizontal portion, a roller journaled in theupstanding portions of the l plates, an arm movable through each slot,

a roller journaled in the upper ends of the 10 arms, and means formoving said arms longitudinally through the slots.

In testimony whereof I aiiiX my signature in presence of tWo Witnesses.
